WILLIAM O. CREE, OF BEVERLY, MASSACHUSETTS.

BLADE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 416,902, dated December10, 1889.

Application filed June 15, 1889. Serial No. 314507- (No model.)

To all whom it may concern:

Be it known that I, WILLIAM O. CREE, a citizen of the United States, anda resident of Beverly, in the county of Essex and State of or articlesof cloth, leather, &c.,although itis.

equally well adapted for otherpurposes, or for holding and securingotherkinds of tools in the handle, as will hereinafter be more fully 'shownand described, reference being had to the accompanying drawings, whereinFigure 1 represents a side elevation of the improved knife -bladeholder, and Fig. 2 represents a central longitudinal section of thesame. Fig. 3 represents a side view of the screw-plug to which thegrooved clampingbars are pivoted. Fig. 4 represents a crosssection onthe line X X, shown in Fig. 2; and Fig. 5 represents a cross-section onthe line Y Y, also shown in Fig. 2.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

a represents a knife-blade or tool that is to be secured in the improvedholder, and b I) represent the internallygrooved clampingbars adaptedtoreceive opposite edges of the blade ain a similar manner to that shownin the patent granted to Samuel A. Cummings, December 5, 1865, No.51,297, said clampingbars having at or near their outer ends the camprojections la b, which come in contact with the internal edges of theslotted capped ferrule 0 when the said clamping-bars are drawn into thehandle, and thereby cause the blade or tool a to be clamped and heldbetween the said grooved clamping-bars in a manner similar to that shownand described in the said Cummings patent.

The handleis composed of two parts (1 and 6, preferably made of wood.The part c has a longitudinal perforation e, of a shape and size adaptedto receive the clamping-bars b b, and to the forward or upper end ofsaid handle part is secured the ferrule c, as shown in Figs. 1 and 2.The handle part d has secured within it the nut f, which latter has acylindrical extension f, adapted to be guided in a corresponding recess6' in the thick end of the handle part e, such recess being preferablylined with a metal sleeve 6 so as to prevent the wearing out of suchrecessed part of the handle 6, as shown in Fig. 2. -In the nut f isscrewed the screw-threaded plug g, which latter has a longitudinalperforation 9, going from end to end of said plug, which perforationserves to receive the ends of the grooved clamping-bars b b, and thelatter are connected to the screw-plug g by means of a pin h, thatpasses through perforations in the plug 9 and clamping-bars I) Z), asshown in Figs. 2, 3, and 4. The pin his arranged parallel with the knifeor blade at, so as to permit the clamping-bars b b to adjust themselvesfreely out and in on said pin, according to the width of the knife orblade that is being used.

The operationof the device is as follows: If a knife or blade is securedin position as shown in the drawings, and it is desired to remove it forthe purpose of inserting another blade, it is only necessary for theoperator to grasp with one hand the handle portion e and with his otherhand to take hold of and turn the handle part d toward the left,by'which means the nut f is turned around the screwthreaded plug g,causing the latter to be moved toward the handle portion 6, and as theclamping-bars b b are connected to said plug said bars will be moved inthe same direction, by which their cam-faces b b are liberated from theedges of the capped ferrule 0, thus allowing said clamping-bars toexpand sufficiently to release the knife or blade a, that may now bedrawn out from or adjusted between the said grooved clamping-bars.

If it is desired to insert a new blade in the holder, such blade ispushed into the longitudinally-grooved bars 17 b as far as may beneeded, after which the operator holds the handle part 6 with one hand,while with the other he takes hold of and turns the handle part 01toward the right, causing the screwplug and clamping-bars to be moved inthe direction shown by arrows in Fig. 2, until the cam-faces b b arebrought sufficiently in contact with the edges in the'capped ferrule tocause the blade ato be clamped firmly between said groovedclamping-bars.

The perforation e in the handle partebein g made flattened section tocorrespond to the Width of the clamping-bars, it will be seen that thelatter are prevented from turning around Wlt-hllLSLld handle part 8 whenthe handle portion (Z and its nut f are turned around the plu'g g, asabove stated.

The clamping-bars b I) being free to adjust themselves in their innerends on the pin h, it will be seen that blades of various widths may beused and that such blade or tool will be held throughout its length(except that portion of it outside of the holder) Within the saidgrooved clamping-bars, thus causing said blade or tool to be rigidlysecured to the holder While the device is in use. In tools of this kindheretofore used the nut for operating the clamping-bars has to bemanipulated bymeans of a screw-driver or similar device, which is objectionable, as such device may not always be handy or be Within thereach of the operator.

In my improved holder I am entirely independent of a screw-driver orsimilar tool for operating the clamp-actuating nut, as all that isneeded is to grasp the handle parts cl and c and to turn one around itsaxis relative to the other in loosening or securing the tool from or tothe holder. In tools of this kind the handle generally terminates in ametal nut or I Washer, usually scored, which is an objectionablefeature, as it is liable to chafe and injure the hand of the operatorwhile using the tool. Such objection is overcome in my invention byhaving the end of the handle part (Z solid and the nut f arranged insideof the same, as shown and described.

WVhat I wish to secure by Letters Patent and claim is The knife-bladeholder, as described, consisting of the grooved clamping-bars b I),having cam projections b b in their outer ends, and having their innerends pivoted Within the longitudinally-perforated screw-threaded plug g,combined with the longitudinallygrooved handle part 6, having the cappedferrule 0, and the handle part cl, having the nut f, surrounding theplug g, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 11th day of Febr'uary, A.D. 1889.
